Title: Process for forming a layered paper web having improved bulk, tactile impression and absorbency and paper thereof
IPC: D21F11/04
Filed: 1976-05-28
Abstract: A wet-laid composite, soft, bulky and absorbent paper structure is prepared from two or more layers of furnish which are preferably comprised of different fiber types. The layers are preferably formed from the deposition of separate streams of dilute fiber slurries, the fibers typically being relatively long softwood and relatively short hardwood fibers as used in tissue papermaking, upon one or more endless foraminous screens. The layers are subsequently combined to form a unitary web, and the layered, unitary web is dewatered by the application of fluid forces. The moist, layered web is thereafter transferred to an open mesh drying/imprinting fabric. The application of a fluid force to the web creates patterned discrete areas of fibers numbering from about 100 to about 3600 per square inch of projected surface area on the side of the web which contacts the drying/imprinting fabric. The undensified discrete areas which correspond to the mesh openings in the drying/imprinting fabric extend outwardly from the fabric side of the layered web and generally assume the form of totally-enclosed pillows, conically grouped arrays of fibers, combinations thereof or the like. Following transfer of the moist, layered paper web to the drying/imprinting fabric, the web is thermally predried to a fiber consistency of at least about 30 percent. The thermally predried, layered paper web may then be compacted in discrete areas corresponding to the knuckles of the drying/imprinting fabric to impart strength and to adhere the web to the surface of a dryer drum for final drying and/or creping. In the alternative, the thermally predried, layered paper web may be finally dried directly on the drying/imprinting fabric without any compaction by the fabric knuckles. In the latter event, the finally dried web is preferably subjected to mechaical micro-creping to impart softness, flexibility and drape to the fnished sheet. The above described layered structures exhibit significantly improved bulk, flexibility, compressibility, drape and absorptive capacity when compared to prior art paper sheets formed by similar processing techniques from a single slurry comprised of a homogeneous mixture of similar fibers. In addition, the structures which are stratified with respect to fiber type typically yield finished paper sheets having significantly improved tactile impression and softness.

IPC: B61L25/06
Filed: 1978-06-20
Abstract: A control system including apparatus for the transmission of information for the control of vehicles travelling in one direction on a guideway. The guideway is broken down into a plurality of groups of uniquely identified sequential blocks. Each block has at least one vehicle detector for detecting the presence of a vehicle and having an operated condition responsive to vehicle detection. Each block further includes a transmitter for providing, to a vehicle within the block, information concerning the block it is in as well as information regarding the identity of the next downstream occupied or unavailable block. To this end, each block has associated with it a word generator for producing a signal identifying the block the word generator is coupled to the block transmitter, which transmitter is only enabled when the vehicle detector is in its operated condition. A communication channel extends in a direction opposite to the direction of travel on the guideway, and each block includes a coupler for coupling the portion of the communication channel co-extensive with the block to the adjacent upstream block. The coupler is responsive to the condition of the vehicle detector for maintaining a connection between the communication channel in the block with the communication channel of the next upstream block, when the vehicle detector is not operated. When the vehicle detector is operated, the coupler connects the output of the word generator to the next upstream block. The transmitter of each block receives another input from the communication channel. In this fashion, a vehicle in any block receives a signal identifying the next downstream occupied block as well as a signal identifying the block it is in.

Title: Marine sewage disposal
IPC: C02F/
Filed: 1980-01-21
Abstract: An activated sludge marine sewage disposal apparatus includes an aeration chamber immediately adjacent to a flooded settling tank, rising above a disinfectant chamber and a holding chamber disposed around the lower part of the tank. Flow from the aeration chamber to the settling tank is through a port in the common wall between the aeration chamber and settling tank, and up inside a pond separated from the rest of the tank by a downwardly flaring baffle of skirt depending from the top of the tank. A single shimmer at the center of the area at the top of the pond picks up floating solids and returns them to the top of the aeration chamber. A vent disposed directly over the shimmer continuously draws off air and gas to the aeration chamber. A sludge return line picks up heavy solids for the bottom of the tank and returns them to the top of the aeration chamber through a riser located in the aeration chamber. Liquid in the settling tank flows out through a submerged perforated pipe into a standpipe in the aeration chamber, with is located centrally in the aeration chamber, and overflows through an inverted U tube, vented to the aeration chamber, the tube connecting to a downcomer sending the liquid back through the common wall to the disinfectant compartment. When sufficient volume of fluid accumulates in the disinfectant compartment, it overflows into a holding tank, from which it emerges via a port.
